F1 chiefs had initially proposed the concept of a banked final flip in a bid to supply a for much longer interval of full-throttle operating than the unique configuration allowed.
With passing locations extraordinarily restricted on the slender circuit, it was felt that this design would at the least give an opportunity of some motion.
Pc simulations present that the flat out banked bend ought to add one other 340 metres of flat out motion – on prime of the 678 metres of straight that follows.
The banking was made so excessive – with a profiling of 32 p.c, the equal of 18 levels – to offer drivers sufficient load by means of the nook to run with DRS open.
Nonetheless, for the inaugural Dutch GP this weekend, the FIA has elected to play it secure and can solely permit DRS to be opened after the nook.
Circuit chief Jan Lammers stated on Wednesday: “That’s the determination of the FIA. They only wish to see the way it goes this 12 months they usually wish to acquire information in actual life.
“They’re not taking any dangers and that’s comprehensible for this primary version in 36 years.”
Craig Wilson, who’s head of auto efficiency at F1 and heads a division there that helps create and take a look at circuit designs, was key to serving to flip the banking concept into actuality.
Final 12 months he spoke in regards to the checks that had been run by means of to permit DRS to be open by means of there.

With the primary concept for a banked nook coming from former F1 race director Charlie Whiting, Wilson’s workforce got here up with an idea they thought would work.
“A remark got here again and stated: ‘may we do banking?” stated Wilson. “I thought of it, and it was: ‘Okay effectively go away it with me, let me work out what degree of banking can be required on the idea of may we, quite than have DRS open after the final flip, may we open DRS by means of the final flip?
“We went by means of it, we used our simulation after which we got here again and stated ‘okay effectively you’d want at the least this degree of banking to have the ability to do it. I had assessed it with two completely different strategies, by way of automobile stability and the aerodynamic loss, and it appears like it may work.
“Then it was a case of, ‘okay effectively can we bodily do it?’
“The fellows at Zandvoort went off, spoke to some individuals and got here again and stated: ‘Yeah, we will do it, we expect we will do it, and we might be very fascinated with doing it.’
“So we had conversations with the FIA to say ‘look, that is what we’re pondering, are you okay with that?’ They stated let’s undergo the numbers, let us take a look at what else is concerned.
“As a course of, we had been getting all the correct individuals collectively and we had been in a position to really provide you with an answer – and a reasonably distinctive answer to that state of affairs.”
